Don't know about the difference in focus between star and planet. I've never been able to get a better shot using the planet to focus on than using a star. To my mind they are both virtually at infinity so the focal point should be the same. As a guide I use the casini division. If it peeks in nice and sharp every now and then I know I'm close. If it's hard to see I usually don't bother imaging.
